Probably the most important thing to do in a RAS is to remove solids as quickly as possible. A swirling solids settling tank would be worth looking at. You would place it in front of your clarifier. A well setup settling tank let's you "flush" the solids out of the bottom as needed, much like flushing a toilet. It really cuts down on the time spent cleaning filter media, and it really helps to keep the whole system running smoothly.
